* Disable [the hypervisor](https://learn.microsoft.com/en-us/troubleshoot/windows-client/application-management/virtualization-apps-not-work-with-hyper-v) and [VBS (Virtualization-Based Security)](https://www.tomshardware.com/how-to/disable-vbs-windows-11).
* If you're looking for a good clean OS image - the same used on arcade cabinets - `Windows 10 IoT Enterprise LTSC` is recommended. Just be mindful, it's not Windows 10 IoT, it's not Windows 10 Enterprise, it's Windows 10 IoT Enterprise LTSC.
* Contrary to popular belief, `IoT Enterprise` is a general-purpose OS with a full desktop environment, and is not too different from full version of Windows. (the non-Enterprise `IoT` SKU is different, however, as it lacks the desktop UI by default).
* Also see *Background services* section below.
* Disable full screen optimizations - right click on spice.exe / spice64.exe, Properties, Compatibility tab, Change settings for all users, and check `Disable fullscreen optimizations`. You have to do this for every instance of spice executable (every place where your game is installed), not just once.
### Background services
If you are failing to keep a steady framerate, check for background services, especially ones that inhibit bursts of CPU usage.
#### Common offenders
* Various Windows background services
* When stutters occur make a note of the time and check Windows Event Viewer (System and Application channels) for events at that time.
* Look for things like:
* Windows Update (set quiet hours or temporarily turn on Do Not Disturb)
* License check events (Security-SPP)
* Windows Defender (add directory exceptions to avoid scanning game data)
* Various file-sharing software like OneDrive, Google Drive, DropBox
* In-game overlay: Discord, NVIDIA, Xbox GameDVR / Game Bar, etc
* RivaTuner Statistics Server (RTSS), MSI Afterburner - occasionally known to cause mystery crashes as well
#### Less common offenders
* OBS - usually doesn't affect game performance, but may cause spicecfg to launch very slowly
* Other games that install kernel-level anti-cheat
* Razer Synapse ([though Razer claims it's fixed in recent versions](https://insider.razer.com/razer-synapse-3-29/synapse-3-high-cpu-wmi-provider-service-43747)). Can also cause issues with audio.
* Oculus app / Meta Quest Link (including the background services that cannot be disabled except to uninstall)

* Display built into laptops tend to be more restrictive about what resolution and refresh rate combinations are supported, so connecting to an external monitor alleviates that.
* Just make sure the right GPU is being used. Some laptops have weird restrictions on which GPU gets used for each HDMI/DisplayPort.
